You can put this solution on YOUR website! Let x=the number; 4x=four times the number;2(x+5)=twice the sum of 5 and that number
And we are told the following:
4x=2(x+5) get rid of parens
4x=2x+10 subtract 2x from each side
4x-2x=2x-2x+10
2x=10
x=5-----------the number
CK
4*5=2*(5+5)
20=20
Hope this helps----ptaylor
